Multiple Choice

Is the following equation balanced?

4Fe + 3O₂ ---> 2Fe₂O₃

• YES

• NO

Multiple Choice

Is the following equation balanced?

Al + O₂ ---> 2Al₂O₃

• YES

• NO

Combination Reactions

• AKA Synthesis reaction

• General Format

   $A\ +B\rightarrow AB$ 

• Rust $Fe\ +O_2\rightarrow Fe_2O$  

Decomposition Reactions

• Decomposition=breaking down

• General Format

   $AB\rightarrow A+B$ 

• Hydrogen Peroxide:  $2H_2O_2\rightarrow2H_2O+O_2$  

Single Replacement Reactions

• One element is replaced in a compound

•  $A+BC\rightarrow B+AC$ 

•  $Example:\ 2K+2H_2O\rightarrow2KOH+H_2$  

• Only works if one element is more reactive than the other (use activity series on page 361 in online textbook)

Double Replacement Reactions

• Two elements switch in both compounds

•  $AB+CD\rightarrow CB+AD$ 

•  $Example:\ HCl+NaOH\rightarrow H_2O+NaCl$  

• Neutralization (water as a product), precipitation (solubility rules on page 372 in online textbook), and gas formation

Combustion Reactions

• Water and Carbon dioxide are the only prodiucts formed!

•  $C_xH_y+O_2\rightarrow H_2O+CO_2$ 

•  $Example:\ CH_4+2O_2\rightarrow2H_2O+CO_2$  

• Burning of Wood or Coal to heat your home. Burning of Petrol or Diesel to run your Car. Combustion of Natural Gas to cook on your stovetop. For the production of energy in thermal power plants. Fireworks
